Background Elderly patients undergo surgery for colorectal cancer more often than younger patients because of the inci dence and prevalence of colon and rectal cancer (CRC).
Anastomotic leakage is the most feared complication after surgery because it impairs postoperative survival, disease free survival rate and recurrence.
A recent metaanalysis shows that interleukin IL6 and IL 10 intraperitoneal levels may be a useful marker to predict the likelihood to anastomotic leakage. Furthermore, the variations of cytokines levels are similar both in serum and intraperitoneal fluid, despite there is a quantitative difference between peritoneal and systemic concentra tions.
For this reason in our Department a prospective study is ongoing to assess if systemic interleukin IL6 and Il10 are a reliable marker to predict anastomotic leakage.
Methods The study group is yet represented by 33 patients: 17 males and 16 females (median age 76, range 70–89). The location of cancer was respectively: 5 (15, 15%) in the rec tum, 15 (45, 45%) in the left colon, 11 (33, 33%) in the right colon, 1 (3, 3%) in the transverse colon, 1 (3, 3%) synchronous in the caecum and the sigmoid colon.
The associated diseases observed were: chronic obstruc tive pulmonary disease, hypertension, diabetes mellitus, ischemic heart disease arterial vasculopathy.
The surgical operations performed were respectively: 11 left colectomies, 8 right colectomies, 2 subtotal colecto mies, 6 segmental resections, 3 anterior resections, 1 bypass anastomosis, 2 abdominoperineal excisions. In our study group we made 31 digestive anastomoses.
Systemic measurements of IL6, IL10, Creactive protein (CRP), lymphocytes and serum albumin were performed with ELISA in the preoperative period (t0), in the first (t1) and seventh postoperative day (t2).
Results In the study group 32 anastomoses were made and we observed only one (3.2%) anastomotic leakage. The CRP serum levels (mg/l) were: t0 24.63 ± 4.17, t1 25.62 ± 5.63, t2 21.5 ± 4.41 in complicated patients and t0 24.64 ± 5.18, t1 24.4 ± 7.15, t2 22.4 ± 7.99 in uncomplicated ones. IL6 serum levels (pg/ml) were: t0 8.13 ± 3.31, t1 145.87 ± 88.62, t2 19.75 ± 23.56 in complicated patients and t0 6.74 ± 4.9, t1 118.36 ± 57.64, t2 19.32 ± 15.08 in uncomplicated ones. IL10 serum levels (pg/ml) were: t0 4.63 ± 2.13, t1 19.52 ± 8.38, t2 5.75 ± 4.23 in complicated patients and t0 16.92 ± 18.10, t1 20.28 ± 18.18, t2 5.2 ± 2.61 in uncomplicated ones. Albumin serum levels (g/dl) were: t0 3.68 ± 0.42, t1 2.34 ± 0.70, t2 2.85 ± 0.83 in com plicated patients and t0 3.71 ± 0.60, t1 2.82 ± 0.54, t2 3.30
